연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A system and method of compressing a video signal can include the steps of: receiving a video signal, the video signal including frames; analyzing, for each frame, the video signal on a macroblock-by-macroblock level; determining whether to downsample a macroblock residual for each of the macroblocks; selectively downsampling a macroblock residual for some of the macroblocks; and coding the macroblocks. A system and method of decompressing a video signal can include the steps of receiving a compressed video signal, the video signal including frames; analyzing, for each frame, the video signal on a macroblock-by-macroblock level; determining whether to upsample a macroblock residual for each of the macroblocks; selectively upsampling a macroblock residual for some of the macroblocks; and decoding the macroblocks.

1. A method of compressing a video signal, the method comprising the steps of: receiving a video signal, the video signal including frames;analyzing, for each frame, the video signal on a macroblock-by-macroblock basis;selecting at least one macroblock as a candidate for downsampling of residual of the macroblocks;comparing a cost of downsampling a macroblock residual in a standard mode to a cost of downsampling the macroblock residual in an alternate mode;downsampling the selected macroblock residual according to the compared cost; andcoding the selected macroblock at one of a full residual resolution or reduced residual resolution. 2. The method of claim 1, comprising the steps of: rearranging each macroblock residual;transforming each macroblock residual; andquantizing each macroblock residual. 3. The method of claim 2, further comprising the step of: transmitting the macroblock residual. 4. The method of claim 1, wherein the downsampling is performed on at least one of inter macroblocks and intra macroblocks. 5. The method of claim 1, further comprising the step of: determining not to downsample some of the macroblock residuals; andcoding some of the macroblocks at full resolution. 6. The method of claim 1wherein the alternate mode is a Reduced Resolution Residual Coding (RRRC) mode. 7. The method of claim 1, wherein implicit signaling is used to indicate when a macroblock is upsampled. 8.
